I've lost 2 flight thanks to Kiwi and had to book a hotel waiting for another flight that I paid by myself, of course. Altogether I've lost more than 500$.
Kiwi refunded me almost a quarter of this money.
DO NOT BOOK WITH THEM!
They didn't seem to care to much about the bills I've sent them for refund.
When choosing the delivery from a closer location, it can be very fast, however you can choose from a different location such as the origin country. Your delivery will take longer, but usually the price is cheaper.
Tip for consumers: If you don't need it urgently, choose to be delivered from the factory warehouse, usually China. You will get a better price.
